Subscribers to The Economist on the iPad complain about the buggy magazine in the reviews section. They have every right to be upset considering the chunk of change they’re throwing down ($130 yearly, $40 quarterly). When I bought an issue, the user guide immediately warned me about an authentication bug.
While page layouts are very clean, navigation seems terribly messy. The magazine doesn’t flow from cover to cover, so you don’t really have a sense of location. There’s practically zero use of multimedia. But people read The Economist not for visuals but for its insightful stories, which, at least, the iPad version delivers.
